Description

Technical Field

[0001] This invention relates to the field of aviation technology, and in particular to a method, system, computer-readable storage medium, and electronic device for troubleshooting aircraft seats. Background Technology

[0002] In the current global air transport industry, wide-body aircraft, due to their larger passenger capacity and long range, are typically assigned to international routes. In contrast, business class, as a crucial cabin class on wide-body aircraft, primarily serves high-net-worth individuals. Therefore, the maintenance standards for business class seats must be the highest, and ensuring their proper functioning is a vital aspect for airlines to improve service quality and maintain their corporate image.

[0003] The adjustment of existing business class seats is usually controlled electrically. If the electric control fails, it will not only seriously affect the overall passenger experience, but may also have a negative impact on the overall image of the airline.

[0004] Aircraft maintenance presents numerous challenges for seat repair. Due to the collaboration of multiple professional teams, the short power-on time of the aircraft, and the unstable power supply, the challenges manifest in two ways: First, while electronics specialists conduct power-on tests during the initial two days of maintenance, the electrical control testing and troubleshooting of business class seats are unique, requiring frequent power on / off cycles and a longer overall power-on duration. Therefore, the initial power-on conditions cannot meet the maintenance requirements for business class seats. Second, given that subsequent aircraft maintenance schedules involve work from other disciplines, the aircraft is often in a power-off state, causing significant inconvenience for electrical control testing of business class seats and further increasing the difficulty of troubleshooting. Summary of the Invention

[0005] The purpose of this invention is to provide a troubleshooting method, system, computer-readable storage medium, and electronic device for aircraft seats. By using frequency converters, identification code tables, and dedicated troubleshooting wires, the troubleshooting process for aircraft seats is no longer limited by the overall power-on time of the aircraft. This effectively improves the efficiency of repair and troubleshooting, avoids errors and omissions, and increases repair reliability.

[0006] A first aspect of the present invention provides a troubleshooting method for aircraft seats, comprising:

[0008] When the power supply drives the aircraft seat, the electronic control function status of the aircraft seat and the indicator light information corresponding to each electronic control component are combined to form a temporary standard code; wherein, the electronic control component includes: main control component, backrest motor, leg rest motor or foot pedal motor;

[0009] Search the standard code table for the fault region information that matches the temporary standard code, and determine whether the fault region information is an empty set;

[0010] If so, then stop the troubleshooting operation;

[0011] If not, then determine the troubleshooting link based on the fault area information, replace the connecting wire in the troubleshooting link with a troubleshooting wire, and perform electrical control tests on the electrical control components in the troubleshooting link to determine the fault location point corresponding to the temporary standard code.

[0012] Optionally, the standard code table is determined by the circuit connection relationship of each of the electronic control components; wherein the circuit connection relationship is obtained by connecting the main control component, the rear support motor, the leg support motor and the foot pedal motor in series.

[0016] When the main control component indicator light and the backrest motor indicator light represented by the third standard code are both in normal condition, the leg rest motor indicator light and the foot pedal motor indicator light are both in abnormal condition, and the electronic control function is in a failed state, the fault area information corresponding to the third standard code is that the leg rest area is abnormal.

[0017] When the main control component indicator light, the backrest motor indicator light, and the leg rest motor indicator light represented by the fourth standard code are all in normal condition, the foot pedal motor indicator light is in abnormal condition, and the electronic control function is in a failed state, the fault area information corresponding to the fourth standard code is that the foot pedal area is abnormal.

[0020] When the fault area information indicates an abnormality in the leg rest area, replace the leg rest motor connection wire with the corresponding leg rest motor troubleshooting wire, or replace the backrest-leg rest adapter connection wire with the corresponding backrest-leg rest adapter troubleshooting wire, and perform an electrical control test on the leg rest motor to detect whether the leg rest motor connection wire, the backrest-leg rest adapter connection wire, or the leg rest motor is a fault location point.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] See Figure 1 This is a flowchart illustrating an embodiment of the aircraft seat troubleshooting method provided by the present invention.

[0053] A first aspect of the present invention provides a troubleshooting method for aircraft seats, including steps S1 to S5, as detailed below:

[0054] Step S1: Convert the voltage of the aircraft's external power supply through the frequency converter and provide input power to the aircraft seats;

[0055] Step S2: When the power supply drives the aircraft seat, the electronic control function status of the aircraft seat and the indicator light information corresponding to each electronic control component are combined into a temporary standard code; wherein, the electronic control components include: main control component, backrest motor, leg rest motor or foot pedal motor;

[0056] Step S3: Search for the fault region information that matches the temporary standard code in the standard code table, and determine whether the fault region information is an empty set;

[0057] Step S4: If yes, then stop the troubleshooting operation;

[0058] Step S5: If not, determine the troubleshooting link based on the fault area information, replace the connecting line in the troubleshooting link with a troubleshooting wire, and perform electrical control tests on the electrical control components in the troubleshooting link to determine the fault location point corresponding to the temporary standard code.

[0059] It should be noted that this embodiment of the invention provides an independent and portable power supply for aircraft seats (e.g., business class seats) via a frequency converter. In other words, the frequency converter converts the voltage of the aircraft's external power source (e.g., a fixed ground power source) to provide a stable input power to the aircraft seats, enabling them to perform various maintenance tasks independently even when the entire aircraft experiences a power outage. Furthermore, when using the frequency converter, its input is connected to the aircraft's external power source, and its output is connected to other electronic components inside the seat (e.g., a seat power module, SPM), allowing current to be directed to the electronic control unit (ECU).

[0060] After powering the aircraft seat, the electronic control system is tested. During this phase, the status of the aircraft seat's electronic control functions and the indicator light information for each electronic component are collected and compiled into a temporary standard code. This temporary standard code maps the current operating state of the aircraft seat. Once generated, the temporary standard code is compared with a predefined standard code table to quickly find the fault area information that matches the current temporary standard code. The standard code table stores the standard codes for all possible faults and their corresponding fault area information, and may even include fault handling measures.

[0061] Next, it is determined whether the matched fault area information is an empty set. If it is an empty set, it indicates that the currently detected operating status matches the normal operating status of the aircraft seat, and no fault has been identified. In this case, the troubleshooting operation can be stopped. If it is not an empty set, it indicates that there is a known fault corresponding to the temporary standard code. By analyzing the fault area information, the specific troubleshooting link is determined, that is, the troubleshooting sequence is determined, as well as the electronic control components and related connecting lines that need to be checked. The automatic troubleshooting equipment (device) or operator will replace the connecting lines in the troubleshooting link with troubleshooting leads and perform electronic control tests on the electronic control components in the troubleshooting link to accurately locate the fault location point corresponding to the temporary standard code.

[0062] It's worth noting that, taking the A330 twin-engine wide-body aircraft as an example, its business class seats number around 20, and the electronic controls for each seat are typically divided into three parts (backrest adjustment, legrest adjustment, and footrest adjustment). Therefore, the one or two days of power-on time provided during the initial stages of aircraft maintenance is insufficient to meet the requirements for testing and troubleshooting the electronic controls for all business class seats. The conventional troubleshooting method involves listing possible causes based on the fault symptoms and prior troubleshooting experience, and then sequentially testing each component in turn. During this process, the aircraft needs to be frequently powered on and off according to the manual.

[0063] In comparison, the embodiments of the present invention can achieve independent power supply to a single seat through a frequency converter, eliminating the need to power the entire machine; at the same time, the application of identification code meter and dedicated troubleshooting wires eliminates the need to sequentially connect components for troubleshooting verification, which effectively improves the efficiency of repair and troubleshooting, avoids errors and omissions, and increases the reliability of repair.

[0064] In an optional embodiment, the standard code table is determined by the circuit connection relationship of each of the electronic control components; wherein the circuit connection relationship is obtained by connecting the main control component, the rear support motor, the leg support motor and the foot pedal motor in series.

[0065] It should be noted that the electric adjustment of aircraft seats (such as business class seats) is usually divided into three parts: backrest electric adjustment, legrest electric adjustment, and footrest electric adjustment. Therefore, the electric control components of the seat include: a main control unit, a backrest motor, and a legrest motor or footrest motor; among which, the main control unit can be an ECU.

[0066] Taking the A330 twin-engine wide-body aircraft as an example, the business class seats are of the S37813-001 series and S37B13-001 series, manufactured by the British company ZODIAC AEROSPACE. Figure 2 The diagram shown is an example circuit diagram of a business class seat in an A330 aircraft provided by this invention. Figure 2 In this system, the main control unit (ECU), the backrest motor, the leg rest motor, and the foot pedal motor are connected in series via their respective connecting wires; the backrest motor corresponds to the backrest motor connecting wire; the leg rest motor corresponds to the backrest-leg rest adapter connecting wire and the leg rest motor connecting wire; and the foot pedal motor corresponds to the foot pedal motor connecting wire.

[0067] In an optional embodiment, the standard code table includes:

[0068] When the main control component indicator light, the backrest motor indicator light, the leg rest motor indicator light, and the foot pedal motor indicator light represented by the first standard code are all in normal condition, and the electronic control function is in normal condition, the fault area information corresponding to the first standard code is an empty set.

[0069] When the main control component indicator light, the backrest motor indicator light, the leg rest motor indicator light, and the foot pedal motor indicator light represented by the second standard code are all in an abnormal state, and the electronic control function is in a failed state, the fault area information corresponding to the second standard code is an abnormal backrest area.

[0070] When the main control component indicator light and the backrest motor indicator light represented by the third standard code are both in normal condition, the leg rest motor indicator light and the foot pedal motor indicator light are both in abnormal condition, and the electronic control function is in a failed state, the fault area information corresponding to the third standard code is that the leg rest area is abnormal.

[0071] When the main control component indicator light, the backrest motor indicator light, and the leg rest motor indicator light represented by the fourth standard code are all in normal condition, the foot pedal motor indicator light is in abnormal condition, and the electronic control function is in a failed state, the fault area information corresponding to the fourth standard code is that the foot pedal area is abnormal.

[0072] It should be noted that, in order to provide a clearer description of the standard code table provided in the embodiments of the present invention, a specific embodiment is provided below for reference, as shown in Table 1.

[0073] Table 1. Standard Code Table for Business Class Seats on A330 Aircraft

[0074]

[0075] In Table 1, "Item" refers to the first step in troubleshooting the seat; "Backrest Plug" is the backrest motor connection cable; "Legrest Plug" is the legrest motor connection cable; and "Foot Pedal Plug" is the foot pedal motor connection cable.

[0076] It should be noted that the first standard code (standard code number ①) corresponds to a normal seat, and its seat circuit diagram is as follows: Figure 3 As shown. The second standard code (standard code number ②) corresponds to an anomaly in the backrest area. The corresponding seat circuit diagram for executing the corresponding item is shown below. Figure 4 As shown. The third standard code (standard code number ③) corresponds to an anomaly in the leg rest area. The corresponding seat circuit diagram for executing the relevant item is shown below. Figure 5 As shown. The fourth standard code (standard code number ④) corresponds to an abnormality in the foot pedal area. The corresponding seat circuit diagram is shown below. Figure 6 As shown.

[0077] In an optional embodiment, the fault location is determined by the following steps:

[0078] When the fault area information indicates an abnormality in the backrest area, the backrest motor connection wire is replaced with the corresponding backrest motor troubleshooting wire, and the backrest motor is subjected to an electrical control test to detect whether the backrest motor connection wire or the backrest motor is a fault location point.

[0079] When the fault area information indicates an abnormality in the leg rest area, replace the leg rest motor connection wire with the corresponding leg rest motor troubleshooting wire, or replace the backrest-leg rest adapter connection wire with the corresponding backrest-leg rest adapter troubleshooting wire, and perform an electrical control test on the leg rest motor to detect whether the leg rest motor connection wire, the backrest-leg rest adapter connection wire, or the leg rest motor is a fault location point.

[0080] When the fault area information indicates an abnormality in the pedal area, the pedal motor connection wire is replaced with the corresponding pedal motor troubleshooting wire, and an electronic control test is performed on the pedal motor to detect whether the pedal motor connection wire or the pedal motor itself is a fault location.

[0081] It should be noted that, based on the structural characteristics of business class seats, this embodiment of the invention designs and manufactures four wires for testing and troubleshooting: a rear-seat motor troubleshooting wire (S37013-159-001), a rear-seat-leg rest adapter troubleshooting wire (S37013-156-001), a leg rest motor troubleshooting wire (S37013-163-001), and a foot pedal motor troubleshooting wire (S37013-150-001); wherein, the rear-seat motor troubleshooting wire (S37013-159-001) is as follows: Figure 7 As shown.

[0082] The above four troubleshooting leads can be used to perform electrical control testing and troubleshooting on business class seats. In other words, after obtaining fault area information by "reproducing the standard code" (i.e., generating a temporary standard code), if you want to further confirm whether it is a motor fault or a related wiring fault, you can use the troubleshooting leads, as follows:

[0083] (1) When the fault area information is abnormal in the backrest area, use the backrest motor troubleshooting wire to replace the original backrest motor connection wire, and then retest the seat electronic control function. If the electronic control is normal, the fault is that the original backrest motor connection wire is abnormal. If the fault persists, the fault is that the original backrest motor is abnormal.

[0084] (2) When the fault area information indicates an abnormality in the leg rest area, first replace the original leg rest motor connection wire with a leg rest motor troubleshooting wire, and then retest the seat's electronic control function. If the electronic control is normal, the fault is caused by an abnormality in the original leg rest motor connection wire; if the fault persists, the fault is caused by an abnormality in the original backrest motor or a abnormality in the backrest-leg rest adapter connection. Next, replace the original backrest-leg rest adapter connection wire with a backrest-leg rest adapter, and then retest the seat's electronic control function. If the electronic control is normal, the fault is caused by an abnormality in the original backrest-leg rest adapter connection; if the fault persists, the fault is caused by an abnormality in the original backrest motor.

[0085] (3) When the fault area information is abnormal in the foot pedal area, use the foot pedal motor troubleshooting wire to replace the original foot pedal motor connection wire, and then retest the seat electronic control function; if the electronic control is normal, the fault is that the original foot pedal motor connection wire is abnormal; if the fault persists, the fault is that the original foot pedal motor is abnormal.

[0089] The standard code parsing module 13 is used to search for the fault area information that matches the temporary standard code in the standard code table, and send the fault area information to the troubleshooting module 14.

[0090] The troubleshooting module 14 is used to determine whether the received fault area information is an empty set; if yes, the troubleshooting operation is stopped; if no, the troubleshooting link is determined according to the fault area information, the connecting line in the troubleshooting link is replaced with a troubleshooting wire, and the electrical control components in the troubleshooting link are tested to determine the fault location point corresponding to the temporary standard code.

[0093] When the indicator lights of the main control component, the backrest motor, the leg rest motor, and the foot pedal motor, represented by the temporary standard code, are all in an abnormal state, and the electronic control function is in a failed state, the temporary standard code is searched in the standard code table, and the obtained fault area information is that the backrest area is abnormal.

[0094] When the temporary standard code represents the main control component indicator and the backrest motor indicator, both are in normal condition, the leg rest motor indicator and the foot pedal motor indicator are in abnormal condition, and the electronic control function is in a failed state, the temporary standard code is searched in the standard code table, and the obtained fault area information is that the leg rest area is abnormal.
